[PATCH v1 0/3] RISC-V ACLINT Support

[Anup Patel]

The RISC-V Advanced Core Local Interruptor (ACLINT) is an improvement
over the SiFive CLINT but also maintains backward compatibility with
the SiFive CLINT.

Latest RISC-V ACLINT specification (will be frozen in a month) can be
found at:
https://github.com/riscv/riscv-aclint/blob/main/riscv-aclint.adoc

This series:
1) Replaces SiFive CLINT implementation with RISC-V ACLINT
2) Refactors RISC-V virt machine FDT generation
3) Adds optional full ACLINT support in QEMU RISC-V virt machine

This series can be found in the riscv_aclint_v1 branch at:
https://github.com/avpatel/qemu.git

To test series, we require OpenSBI and Linux with ACLINT support which
can be found in riscv_aclint_v1 branch at:
https://github.com/avpatel/opensbi.git
https://github.com/avpatel/linux.git
